After his introduction in class reaches a zealous climax, a fellow student named Hiroshi Miwa looks up to him, while the rest of the class becomes even more terrified. Eventually, Akuto slips up when he volunteers for "cleaning duty", which is slang in the academy for becoming a "cleaner", an assassin that maintains the school's secrets. This infuriates Junko, who challenges him to a duel that ends with Akuto accidentally destroying the classroom in a magical explosion. His later attempts to reconcile with Junko at her dorm again launch her into a murderous frenzy, resulting in a chase through the woods. There, Akuto runs into Kena Soga mid-fight, and she resolves to protect him for personal, though unspecified reasons. She is unable to do so, and Akuto again ends the fight with another freak explosion. Immediately after, he is greeted by Korone, an "observer".

As an emergency way to reconcile with Junko, she also gives him a two-shot magical gun that fires medicinal tablets, which she claims will allow the two people shot by it to understand each other's feelings. On the way back, he is tackled by Kena, still fleeing from the puppy, and is rendered visible and exposed in clear view of the now-reactivated Korone. In exchange for testifying to Korone that Akuto did not try to molest her, Kena requests his friendship, which he agrees to.

The meeting with Junko turns out to be an ambush by members of the underground, and Akuto swiftly beats them, only for Junko to appear when the dust settles. Mistaking the act as a wrongdoing, she publicly calls Akuto out for punitive justice, and together with a large crowd of students, chase Akuto around the school. Kena intervenes at the last moment before Junko can complete her punitive justice. Junko admits that the situation got out of hand and that she was partly responsible for the misunderstanding that prompted the mob to come after Akuto, only to have the mob call her out for turning back to Akuto's side.
